As some of you know I recently transitioned from my plastic 3l intake to the st220 intake. I have 03 valve covers, 02 f150 tb. Have been experiencing a idle hang then tends to drop after a few moments. Some longer then others. No jumping around pretty steady. New iac 04 mazda mpv, new tps for the f150. Tracked all hoses but one for my pcv on the back side. My boost guage is hooked to its own port on the bottom of the intake and it's holding steady about 21-22 at idle. Now I have tried a different pcv setup mounting my pcv valve to feed grin the valve cover. Any thoughts would be appreciated.
